Salsnes Filter – Separation, Thickening and Dewatering



A Salsnes Filter system combines three critical processes into one compact unit – solids separation, sludge thickening and dewatering. The rotating filtermesh removes >50% TSS, and >20% BOD from effluent and produces drier sludge (20-30% dry matter). It’s the only filter design that can replace conventional primary treatment and fulfill the EU regulations on primary treatment.

Cost-effective, compact, high-performing, chemical-free and sustainable, the Salsnes Filter system defines eco-efficient.

Compared to conventional primary treatment, a salsnes filter system can offer:

  • 30 – 60% lower investment cost
  • 1/10th land requirement
  • Integrated thickening and dewatering
  • Significantly lower lifecycle cost
  • Less civil works
  • Higher removal of TSS
  • Fully-automated equipment
  • Fast and easy maintenance
  • Lower operating costs (no chemical to purchase)
  • Smaller secondary/biological treatment processes

Applications:

  • Municipal wastewater treatment
  • Industrial wastewater treatment

    • aquaculture
    • tanneries
    • pulp & paper
    • food processing>
